Abstract (en)
[origin: WO2011092025A1] The invention relates to an absorbent structure having a sequence of layers, comprising at least one first and one second outer layer and at least one liquid storage layer arranged therebetween, wherein the layers are arranged on top of each other and form a layer structure, wherein at least the liquid storage layer comprises a cellulose material, preferably cellulose fibers, and a superabsorbent polymer SAP, preferably SAP particles and/or SAP fibers, wherein the liquid storage layer comprises at least less, preferably no, binder than liquid-storing layers of the absorbent structure adjacent to the liquid storage layer. The absorbent structure has particularly high flexibility in the wet and the dry state. It can preferably be used in disposable items. The invention further relates to a method for producing the absorbent structure and to a device for producing same.
